AbstractAbstract PDF
PURPOSE
This study was conducted to investigate and identify an appropriate fracture treatment method by analyzing patients in whom a femoral incompetence fracture occurred after receiving a long-term bisphosphonate administration.
MATERIALS AND METHODS
The subjects of this study were 13 cases out of ten patients among those who had a history of receiving bisphosphonate for more than five years and had a fracture or an imminent fracture with a characteristic radiological finding in the femoral subtrochanteric region and the interfemoral region. The period of the drug administration, bone density, the existence of a prodromal symptom, and bilateral fracture were investigated.
RESULTS
In seven out of the 13 cases, the patients complained of painat the femoral and pelvic parts as a prodrome (53.8%), and three of them showed a bilateral fracture (30%). An imminent fracture with a prodrome was observed in six cases (46.2%); for three of these cases, a prophylactic fixture pexis was performed by inserting a metal nail into the medullary cavity, and in two out of these three, a complete fracture was found within 11 months on average (3 to 19 months). In the three prophylactic fixture pexis performed cases, no postoperative complications were found, and a radiological finding of concrescence was seen within one year after the operation. Among the nine operation performed cases after the fracture, non-union was found in two.
CONCLUSION
In the patients who have received bisphosphonate for a long periodof time, a prodome may be a useful indicator of a fracture in the femoral subtrochanteric region and the interfemoral region; therefore, a careful observation is necessary. A prophylactic internal fixation is recommended for patients with imminent fracture with a prodome since they have a high risk of a complete fracture is high in them.

Functional Outcomes of Percutaneous K-Wire Fixation for Distal Radius Fractures with or without Osteoporosis
Ki Chan An, Gyu Min Kong, Jang Seok Choi, Hi Chul Gwak, Joo Yong Kim, Sung Yub Jin
J Korean Fract Soc 2013;26(4):248-253.   Published online October 31, 2013
DOI: https://doi.org/10.12671/jkfs.2013.26.4.248
AbstractAbstract PDF
PURPOSE
To determine the influence of osteoporosis on the results of percutaneous K-wire fixation for distal radius fractures.
MATERIALS AND METHODS
Between March 2007 and February 2011, Fifty seven patients who underwent fixative surgery with K-wires after closed reduction and those available for follow-up for at least 6 months were reviewed. They were divided into the two groups of T score -3 or more (group 1) and T score less than -3 (group 2). These groups were compared by the range of motion of the wrist and Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiologic evaluations consisting of radial length, radial inclination and volar tilt were compared. In group 1 with 34 cases, the average age was 65.4 years (50 to 78 years) and T score was -1.97 (-0.1 to -2.93). In group 2 with 23 cases, the average age was 74 years (54 to 89 years) and T score was -4.11 (-3.1 to -6.97).
RESULTS
There was no statistical difference between group 1 and group 2 in terms of range of motion, DASH score and radiologic evaluations.
CONCLUSION
In the case of no volar side cortical comminution, percutaneous K-wire fixation can be applied for the treatment of distal radius fracture with osteoporosis.

The Fate of Butterfly Fragments in Extremity Shaft Comminuted Fractures Treated with Closed Interlocking Intramedullary Nailing
Ki Chan An, Yoon Jun Kim, Jang Suk Choi, Seung Suk Seo, Hi Chul Gwak, Dae Won Jung, Dong Woo Jeong
J Korean Fract Soc 2012;25(1):46-51.   Published online January 31, 2012
DOI: https://doi.org/10.12671/jkfs.2012.25.1.46
AbstractAbstract PDF
PURPOSE
For conservative treatment of shaft fractures, the butterfly fragments that were somewhat larger in the closed intra-medullary (IM) nailing. The results of treatment were monitored using radiography separately for the weight-bearing femur and non-weight-bearing humerus.
MATERIALS AND METHODS
27 from Group I and 31 from Group II. In the two groups, the displacement and angulation changes in the fragments, and the degree of improvement of these two factors, were compared using follow-up radiography.
RESULTS
The mean angulation of fragments in Groups I and II were 9.2degrees and 9.6degrees, and the mean degree of displacement of the fragments in Groups I and II were 16.7 mm and 21.2 mm, respectively. Follow-up radiography showed that the above factors improved in both groups. The degree of displacement was significantly lower in the normal cases than in the complicated cases (p=0.001).
CONCLUSION
Displacement and angulation gradually improved in both groups. It was found that the degree of displacement after the initial reduction is more important than the influence of anatomical position or weight bearing. This indicates that care should be taken when inserting IM nails to prevent displacement or angulation.

Relationship between Lamina Fractures and Dural Tear in Low Lumbar Burst Fractures
Ki Chan An, Dae Hyun Park, Yong Wook Kwon
J Korean Fract Soc 2011;24(3):256-261.   Published online July 31, 2011
DOI: https://doi.org/10.12671/jkfs.2011.24.3.256
AbstractAbstract PDF
PURPOSE
To investigate the relationship between the greenstick laminar fractures and the dural tear in low lumbar burst fractures and their optimal treatment.
MATERIALS AND METHODS
We enrolled 51 patients (52 cases) who had been diagnosed with low lumbar burst fracture from June 2003 to May 2007. The average age was 39 years (range, 22 to 58), 30 male patients (58.8%), and 21 female patients (41.2%). Average follow-up periods was 19 months (range, 11 to 45). Lumbar CT scan were taken 1 mm slices in precision for all patients. We judged it incomplete fracture if lumbar CT scans show loss of cortical continuity over 3 slices if there is an aggrement of two among one radiologist and two orthopaedic surgeons reached a consensus. Dural tear and entrapment of nerve root were confirmed intraoperatively by the senior surgeon.
RESULTS
In 52 burst fractures, complete lamina fractures occurred in 21 cases and there were green stick laminar fractures in 14 cases. Neurologic defect has been found in 12 cases, 5 (63%) from complete laminar fractures and 3 (37%) from green stick laminar fractures. Dural tears has been detected in 9 cases (26%), 4 (19%) from complete laminar fractures and 5 (36%) from green stick laminar fractures.
CONCLUSION
Dural tear and nerve root entrapment can be accompanied in patients with green stick fracture. There is necessary to consider the possibility of dural tear and nerve root entrapment before operation and to indentify carefully to the presence of nerve root entrapment during operation.

Autogenous Iliac Bone Grafting for the Treatment of Nonunion in the Hand Fracture
Joo Yong Kim, Young Keun Lee, Ki Chan An, Tae Woo Sung
J Korean Fract Soc 2011;24(2):163-168.   Published online April 30, 2011
DOI: https://doi.org/10.12671/jkfs.2011.24.2.163
AbstractAbstract PDF
PURPOSE
To evaluate autogenous iliac bone graft for nonunion after hand fracture.
MATERIALS AND METHODS
From October 2006 through September 2008, we analyzed 35 patients, 37 cases of autogenous iliac bone graft for nonunion after hand fracture that have followed up for more than 12 months. We analyzed about etiology, fracture site, initial treatment, time to bone graft, grafted bone size, grafted bone fixation method, radiologic time of bony healing and bone union rate retrospectively. Also we evaluated VAS and range of motion of each joints (MCP, PIP, DIP) at final follow-up assessment.
RESULTS
Etiology was open fracture 23 cases (62.2%), crushing injury 12 cases (32.4%), direct trauma 2 cases (5.4%). Fracture site was metacarpal bone 7 cases, proximal phalanx 17 cases, middle phalanx 8 cases, distal phalanx 5 cases. Time to bone graft was average 20.7 weeks. Grafted bone fixation method was fixation with K-wire 27 cases (73.0%), fixation with only plate 6 cases (16.2%), fixation with K-wire plus plate 2 cases (5.4%), fixation with K-wire plus cerclage wiring 2 cases (5.4%). Grafted bone size was average 0.93 cm3 and bony union time was average 11.1 weeks and we had bone union in all cases.
CONCLUSION
Autogenous iliac bone graft is the useful method in the reconstruction of non-union as complication after hand fracture.
